The interactions view for a constituent is a listing of all communication and action for a constituent. It currently lists all interactions in ascending order, so the oldest interaction is first. However, it should be listed in descending order so that users can see the most recent interaction at the top of the list. This has already been corrected in version 2.93 but is still occurring in earlier versions.
